SPECIFICATION forming part of Letters Patent No. 776,165, dated November29, 1904.

Application filed January 23, 1901. Serial No. 45,037. (No model.)

10 all whom, it 'IIl/(b/j concern:

Be it known that we, H EREEET BAKER and GEORG N. BAKER, of Syracuse, inthe county of Onondaga and State of New York, have invented certain newand useful W'heeled Scrapers, of which the following is a specification.

. Our invention has forits object the production of a wheeled scraperwhich is strong and durable and requires but a minimum exertion on thepart of the operator when the tray is being filled and while the same isbeing raised out of the ground; and to this end it consists in certainnovel combinations and devices as I 5 hereinafter fully described, andpointed out in the claims.

Figures 1 and 2 are respectively top plan and side elevation, partlybroken away, of our scraper. Figs. 3 and A are additional sideelevations, partly broken away and in section, of said scraper, the traybeing shown in Fig. 3 as receiving its load and in Fig. 4 as havingdischarged said load. Fig. 5 is a top plan view, partly broken away andin section, of the detached axle, the wheel-hubs, and the front end ofthe lever. Fig. 6 is a side elevation of the parts seen in Fig. 5. Fig.7 is a sectional view taken on line 7 7 Fig. 5. Figs. 8, 9, and 10 arerespectively top plan, front elevation, and side elevation of thedetached tray. Figs. 11 and 12 are respectively top plan and sideelevation of the detached lever. Figs. 13 and 14 are respectively topplan and side elevation of the detached rear end of the draft member, aportion thereof being indicated by dotted lines.

Our scraper consists, essentially, of supporting-wheels A, an axle B, atray C, a lever D, a draft member E, means for causing thefor wardmovement of the draft member to raise the tray out of the ground, andmeans for preventing the draft=member from raising the tray out of theground during the filling of said tray.

The supporting-wheels A are of any desirable form, size, andconstruction, being here shown as formed with hubs a, having their innerends provided with annular shoulders 64.

The hubs a are prevented from end wise movement by connecting members Aand are provided with internal chambers which receive the ends of theaxle B and are formed. with closed outer ends. Said axle B supports theconnecting members A, previously mentioned, and, connects the wheels A,which are generally loosely mounted thereon. As best seen in Figs. 1 and5, the axle B is provided with cranks b, arranged at the inner sides ofthe wheels A and connected by an intermediate portion 7/ of the axle.

The trayC is formed with bottom, side, and rear walls, is open at itsfront end and its top, and is provided with connecting-pieces 0, handlesc, and shoulders o 0 Said connectingpieces 0 are arranged insubstantially upright planes, are fixed to the outer face of the frontpart of the tray C, and extend upwardly above the contiguous portions ofthe upper edge of the tray. The portions of the connectingpieces 0extending above the upper edge of the tray thus form, essentially,upwardlyprojecting arms for the tray. The handles 0 are of any desirableform, size, and construction. The shoulders 0 project laterally fromopposite sides of the t 'ay C in advance of the connecting pieces a, andthe shoulder c is formed with a substantially horizontal lower face anda top face inclined forwardly from the outer edge of said lower face.

As best shown in Fig. 2, the lever l) is supported on the axle B withits axis substantially coincident with the axis of the axle B, extendsforwardly and rearwardly from said axle, and forms means for forcing thesupplemental draft members F and the links Cr, previously described,from their operative position. The portion of the lever D in front ofthe axle B is extended downwardly toward its front end, supports thetray C, and consists of opposite arms d, pivoted at their extremities tothe upper ends of the connectingfleece 0 above the upper edge of thetray. Said lever Dis preferably provided with upwardly extending arms dand a depending arm d. The inner faces of the arms (Z are formed witheycsid for receiving the cranks Z/ of the axle B, and

the front ends of said arms (Z are provided with shoulders d forengaging the upper edge of the tray and the front edges of theconnecting-pieces c in advance of the pivotal point of the tray and thelever D and limiting the forward movement of the rear end of the leverD. The depending arm (Z is suitably pivoted to the contiguous portion ofthe lever D and is provided with a plurality of shoulders (Z arrangedone above the other and adapted to engage the lower face of the shoulder0 upon the tray C.

As preferably constructed the lever D consists of a plurality ofsections (Z (Z d, each having branches arranged at substantially rightangles with each other. Corresponding branches of the sections (Z (Zextend forwardly substantially parallel with the line of draft, andtheir outer ends form the portions or arms (Z of the lever D extendingin front of the axle B. The other branches of said sections (i d arelapped upon each other, one of said other branches being formed with alaterallyextending part (Z engaged with the end edge of the other ofsaid branches and with asec- 0nd part, (Z extending rearwardly in aplane substantially parallel with the line of draft and midway betweenthe planes of the forwardlyextending branches of the sections CZ (Z Onebranch of the section (Z is lapped upon the part (Z of the section (Zand the other branch of said section (Z is lapped upon the adjacent orrear branch of the section (Z The draft member E, which is pivoted tothe tray 0 at a point in advance of the axle B and beneath the pivotalpoint of the tray C and the lever D in proximity to the upper edge ofthe tray, is usually provided with opposite arms 6, having their rearends pivoted to the connecting-pieces 0 by pivotal pins fixed relativelyto the tray and their intermediate portions movable into engagement withthe shoulders 0 for limiting the downward movement of the draft member Eindependently of the tray. As preferably constructed the draft member Eis provided with an upwardly-extending stop-arm e for preventing therearward or return movement of the rear end of the tray after thedischarge thereof and with loops 6 projecting from the inner sides ofthe front ends of the arms a. Said draft member E consists of a centrallongitudinal section 6 front sections 8, arranged on opposite sides ofthe section 6 and formed with front portions lapped upon opposite sidesof the central section 0 intermediate portions extending rearwardly fromthe central section 6 and rear portions extending rearwardly beyond therear end of the central section a in planes substantially paralleltherewith and forming the opposite arms 6, intermediate sections 6",formed with front portions lapped upon opposite sides of the centralsection 0 at'the rear of the corresponding portions of the frontsections 6*, intermediate portions extending laterally from said section0 and rear portions lapped upon the inner faces of the rear portions ofthe front sections 6*, and a rear section a, having its central partprovided with surfaces engaged with the end and sides of the rear end ofthe section 6 and having rearward extensions lapped upon the inner facesof the rear portions of the sections 6*.

The means for causing the forward movement of the draft member E toraise the tray C out of the ground consists of the means previouslydescribed for connecting said tray to the axle B and to said draftmember.

The means for preventing the draft member E from raising the tray out ofthe ground during the filling of said tray consists of supplementaldraft members F and links G. Said supplemental draft members F, whichform additional means for connecting the tray C and the draft member E,are here illustrated when in operative position, Fig. 3, as having theirrear ends pivoted to the tray C beneath and in advance of the pivotalpoint of said tray and the draft member E, as inclined upwardly andforwardly, and as having their front ends detachably engaged with theloops 0 upon the draft member E. The links G are shown as having theirfront or lower ends pivoted to the supplemental draft membersF above andin advance of their pivots, as inclined upwardly and rearwardly, and ashaving their rear or upper ends secured to the lever D by pivotal pinsarranged at the rear of a line, as 1, Fig. 3, drawn through the axis ofthe axle B and the pivotal point of the links G and the supplementaldraft members F when the links G are in their operative position.Rearward movement of the rear or upper ends of the links G is preventedby the shoulders (F, which limit the forward movement of the rear end ofthe lever D, as previously described.

In the use of our wheeled scraper the operator disengages the arm (Zfrom the shoulder 0 whereupon the tray falls to the ground and the leverD swings on the axle B until its shoulders (F engage the upper edge ofthe tray and the front edges of the connectingpieces 0. As the draftmember E is moved forwardly the front end of the tray enters the groundand said tray is filled. During the filling of the tray the draft memberE is connected thereto by the pivotal pins for said draft member and bythe supplemental draft members F. The means connecting said tray to theaxle and pivoting the tray to the draft member tends during the fillingof the tray to raise said tray out of the ground and force the rear endof the lever D downwardly and rearwardly; but at the same time thesupplemental draft members F and the links G transmit to the lever D atthe rear of the axis of the axle B strain which tends to force the rearend of the lever D forwardly and upwardly, and thus counteracts theoperation of said means, tending to raise the tray out of the ground.When the tray is filled, the operator pulls the rear or free end of thelever l) rearwardly and downwardly, thus forcing the pivotal point ofthe links (3i and the lever l) in front of a line, as 1, drawn throughthe axis of the axle B and the pivotal point of the links (Sr and thesupplemental draft members F, whereupon the supplemental draft members Fand the links G are out of their operative position. As the free end ofthe ,lever is moved rearwardly and downwardly the tray is readilyraised, this action being greatly facilitated, especially during themovement of the front end of the tray out of the ground, by the meansconnecting the tray to the axle 13 and pivoting the tray to the draftmember E. The filled tray is held in its elevated position by theengagementof the shoulders (Z of the arm d with the shoulder c, andshould the operator be unable to readily raise the tray with a singleeffort to the limit of its upward movement he may engage the lowermostshoulder of the arm (6 with the shoulder c and then rest himselfmomentarily before additionally raising said tray. When the place ofdumping is reached, the tray is discharged in the usual manner by movingthe free end of the lever upwardly and forwardly and by moving the draftmember E forwardly. The discharged tray is then held by the stop-arm inits position assumed during the discharge thereof.

The construction and operation of our wheeled scraper will now bereadily understood upon reference to the foregoing de scription and theaccompanying drawings, and it will be evident that considerable changemay be made in the relative construction and arrangement of thecomponent parts of said scraper without departing from the spirit of ourinvention.
